Can DNA help track down your soul mate?

LOS ANGELES What's on your checklist? Tall, dark, funny, rich, brains or brawn? Single and 35, Angie Paradiso has gone on plenty of dates and is on a mission to find her perfect match.

The answer to true love could be in your genes. A DNA test from claims to measure how compatible two people are by comparing their immune system genes. Angie agreed to put it to the test with her current flame, Stewart.

"He's got a lot of things that I've always been looking for. It's really new still and we've been on four dates so far," Angie said.

So far so good, but what do their genes have to say?

After a series of measures, such as level of attraction, symmetry of attraction and even the probability of a successful pregnancy, Angie and Stewart scored an overall 80 percent in compatibility.

According to experts, our bodies sense the differences between our immune systems and other people's immune systems, and we are naturally attracted to people with genes different than our own. The biological reason for that is more gene diversity ensures better resistance to disease, which is another way of saying opposites really do attract.

So, how does the test work for a couple who's already married?

What's Stephen and Marguerite Saker's secret to lasting love? Does their DNA match up? Their overall score was 70 percent, and they've been married for 27 years.

Experts say that if you take a DNA test, take it with a grain of salt.

"It is as if somebody said to you, 'I'm going to give you a test for whether you like dark chocolate or milk chocolate and you're going to pay money to have this test,' when it would be a lot more fun and a lot more economical to just try the dark chocolate and try the milk chocolate," explained Carol Lauer, a professor of anthropology.

Back to our dating couple. Will Angie stick with Stewart?

"Yeah, definitely," said Angie.
